    Risk, Cost and Offsetting: A Reply to Hill
    Ethics, Policy and Environment. forthcoming.
    In ‘Offsetting and Risk Imposition,’ we argued that when carbon emissions are accompanied by offsetting, this can result in a set of actions that worsens no one’s prospect, and therefore imposes no risk. We argued that this is true for some forms of offsetting but not others. Here, we reply to the criticisms of that argument that Scott Hill makes in ‘No Special Morality for Carbon Emitting,’ and examine more closely the relationship between risk-imposition and the worsening of prospects.

    Concern, Respect, and Cooperation
    Oxford University Press. 2018.
    Three things often recognized as central to morality are concern for others’ welfare, respect for their self-expression, and cooperation in worthwhile collective activity. When philosophers have proposed theories of the substance of morality, they have typically looked to one of these three sources to provide a single, fundamental principle of morality—or they have tried to formulate a master-principle for morality that combines these three ideas in some way. This book views them instead as thre…Read more

    Sympathy, Discernment, and Reasons
    Philosophy and Phenomenological Research 68 (1): 37-62. 2007.
    According to “the argument from discernment”, sympathetic motivation is morally faulty, because it is morally undiscriminating. Sympathy can incline you to do the right thing, but it can also incline you to do the wrong thing. And if so, it is no better as a reason for doing something than any other morally arbitrary consideration. The only truly morally good form of motivation–because the only morally non‐arbitrary one–involves treating an action's lightness as your reason for performing it. Th…Read more

    In general, otherwise permissible actions do not become wrong when agents act on bad attitudes. But cases of discrimination can be exceptions to this generalization. It could “be morally permissible for someone to rent her house to any one of several prospective tenants but not morally permissible to refuse to rent it to one of those people because of his race” (Scanlon 2008: 71). These two claims are plausible and widely accepted, but they call for explanation. Why is it that in some cases of d…Read more
  • Considering durability in carbon dioxide removal strategies for climate change mitigation
    with Charlotte Streck, Minoli Sara, Christian Barry, Stephanie Roe, Matthew Brander, Solene Chiquier, Peter Ellis, Jason Funk, Matthew Gidden, Matthias Honneger, Tracy Johns, Deborah Lawrence, Eve Tamme, and Daniel Zarin
    Climate Policy 1 1-9. 2025.
    This Perspective describes the various dimensions of Carbon Dioxide Removal (CDR) durability and interprets them in the context of current policy making. Durability – together with scalability and sustainability – is an essential condition of CDR. It depends on (i) the duration of CO2 storage and (ii) the risk of reversing such storage. The risk profile of durability varies widely across CDR methods. Because engineered, novel CDR methods involve more stable forms of CO2 storage than nature-based…Read more

    States and other climate actors now commonly set ‘net zero’ targets – pledging that, by a certain date, they will put no more carbon into the atmosphere than they take out. However, there is controversy over what exactly should count as attaining such targets. The method of emissions accounting that states currently use – territorial emissions accounting – is often criticized as problematic, but a fully satisfactory explanation of the problem is needed. We argue that the key both to understandin…Read more

    Contractualism as Meta-Ethics
    In David Copp & Connie Rosati (eds.), The Oxford Handbook of Metaethics, Oxford University Press. forthcoming.
    T.M. Scanlon’s contractualism holds that an action is morally wrong when and because it is ruled out by any set of principles for the general regulation of behaviour that no one could reasonably reject as a basis for informed, unforced, general agreement. This Contractualist Thesis offers a powerful normative ethical theory. Yet Scanlon’s case for it also comes from its help in answering a question that is more naturally classified as metaethical: what account can we give of what wrongness is th…Read more

    Neutral and Relative Value
    In Iwao Hirose & Jonas Olson (eds.), The Oxford Handbook of Value Theory, Oxford University Press Usa. pp. 96-116. 2015.
    This chapter examines the distinction that is sometimes drawn between neutral and relative attributions of value. It asks whether a plausible interpretation can be found for claims about relative value; whether an interpretation can be found for claims about neutral value which best captures the thoughts that people express by using this distinction; whether the distinction can be used to produce a satisfactory way of formulating a relative-value consequentialist theory; and whether a theory of …Read more

    Problems of Demandingness
    In The Moral Demands of Affluence, Oxford University Press Uk. 2006.
    Objections to demanding moral outlooks are surveyed. The Extreme Demand does not rely on substantial consequentialist or other theoretical assumptions about the connection between morality and impartiality. Seven requirements for a successful argument against the Extreme Demand are identified. The argument developed in the following chapters will have affinities with arguments developed by Kant and Williams, but will aim to overcome problems with those arguments.

    Requirement
    In The Moral Demands of Affluence, Oxford University Press Uk. 2006.
    We have an argument for rejecting an iterative but not an aggregative approach to the life-saving analogy. This means that, while Chs 7–9 show that certain forms of personal spending are morally defensible, the life-saving analogy still supplies us with grounds for thinking that other forms of personal spending are not. Some of the main practical implications of the resulting view are spelled out. The resulting view is not puritanical, but is still demanding in the constraints it places on livin…Read more

    Overview
    In The Moral Demands of Affluence, Oxford University Press Uk. 2006.
    The final chapter explains the relationship between the two parts of the book: it explains how Part II has refuted the iterative argument for the Extreme Demand in Part I. It also explains the qualified nature of the conclusion that has been reached: it is a conclusion about the requirements of beneficence, not justice; and it is not the conclusion that morality can never demand extreme personal sacrifices. The implications for direct life-saving action are discussed, and the main strengths of t…Read more

    Showing that the Extreme Demand can be rejected from an appropriately impartial point of view would constitute a decisive objection to it. This would undermine the case for thinking that it could be a demand of either fairness or beneficence. An ‘appropriately’ impartial point of view, for the purposes of this argument, is a point of view of impartial concern for other people’s interests.

    Objections to Aid
    In The Moral Demands of Affluence, Oxford University Press Uk. 2006.
    Various arguments are often given for thinking that aid agencies do no overall good to the poor. The economic and political grounds for thinking this are surveyed in this chapter. It is argued that the claims needed for a cogent objection to humanitarian aid are too strong to be plausible. And even if they were right, they would at most show that we should be helping in some ways rather than others: they would not show that there is nothing we can do to help.

    Important personal goods – goods such as friendships and commitments to personal projects – are constituted by personal partiality. Such goods clearly ground requirements of beneficence – they supply the interests for the sake of which we should help other people. However, accepting this is not consistent with the Extreme Demand, which requires us to lead altruistically focused lives. So the Extreme Demand should be rejected.

    Saving Lives
    In The Moral Demands of Affluence, Oxford University Press Uk. 2006.
    Much of the work of aid agencies aims to prevent threats to life, rather than to save lives. And even when an aid agency’s activity does save life, it might be doubted whether my contribution to an agency’s pool of funds will itself benefit anyone significantly. However, whether or not that is true, an argument from the life-saving analogy will still support a collective requirement of beneficence on us as a group; and fairness will require me to contribute to discharging that requirement. The c…Read more

    The Extreme Demand
    In The Moral Demands of Affluence, Oxford University Press Uk. 2006.
    How far do the demands generated by the life-saving analogy extend? Although the requirement on me to give money to aid agencies is a requirement that I contribute to what we all ought to be doing, that does not mean that, when others are not complying, I am required to do no more than my ‘fair share’. Two further approaches to the life-saving analogy need to be considered: an iterative or an aggregative approach. A case can be given for favouring the iterative approach. But the conclusion to wh…Read more

    Permission
    In The Moral Demands of Affluence, Oxford University Press Uk. 2006.
    How far can the argument against the Extreme Demand be extended? If living one kind of life, or pursuing one kind of good, is better than the alternatives in a significant enough way to ground requirements of beneficence on others to help me, it cannot be wrong for me to refuse to forgo it to help others. Moreover, there are some kinds of lives, and some kinds of goods, that are morally defensible even when there are alternatives that would be no worse for me. This generates neither an ultra-per…Read more

    An Argument from Beneficence
    In The Moral Demands of Affluence, Oxford University Press Uk. 2006.
    The failure to save someone’s life directly is wrong because it is a failure of beneficence. The features that make it a failure of beneficence are also features of not helping people at a distance: they are present when the help we can give is indirect as well as when it is immediate. So not helping people at a distance is wrong too. The methodological challenge of Ch.1 can be answered.

    Discriminate Virtue
    Australasian Philosophical Review 6 (2): 180-188. 2022.
    ABSTRACT Glen Pettigrove’s ‘What Virtue Adds to Value’ maintains that sometimes virtue is fundamental in the order of value, and that we should reject the general thesis that the value of our responses depends on their proportionality to the value of the objects toward which they are directed. He argues that this view is needed to account for the moral phenomena surrounding love, forgiveness and ambition. I object that his view is unable to explain the forms of discrimination that distinguish th…Read more

    Weighing Reasons

    There is a difference between acting with a probability of making a difference to who is harmed, and worsening someone’s prospect. This difference is relevant to debates about the ethics of offsetting, since it means that showing that emitting-and-offsetting has the first feature is not a way of showing that it has the second feature. In an earlier paper, we illustrate this difference with an example of a lottery in which you shake the bag from which a ball will be drawn to determine the identit…Read more

    Stupid Goodness
    In Karen Jones & François Schroeter (eds.), The Many Moral Rationalisms, Oxford University Press. pp. 227-246. 2018.
    In _Paradise Lost_, Satan’s first sight of Eve in Eden renders him “Stupidly good”: his state is one of admirable yet inarticulate responsiveness to reasons. Turning from fiction to real life, this chapter argues that stupid goodness is an important moral phenomenon, but one that has limits. The chapter examines three questions about the relation between having a reason and saying what it is—between normativity and articulacy. Is it possible to have and respond to morally relevant reasons withou…Read more

    Participatory Moral Reasons: Their Scope and Strength
    Journal of Practical Ethics. forthcoming.
    A familiar part of ordinary moral thought is this idea: when other people are doing something worthwhile together, there is a reason for you to join in on the same terms as them. Morality does not tell you that you must always do this; but it exerts some pressure on you to join in. Suppose we take this idea seriously: just how should it be developed and applied? More particularly, just which groups and which actions are the ones with respect to which you have participatory moral reasons? And jus…Read more

    The moral, the personal and the political
    In Igor Primoratz (ed.), Politics and morality, Palgrave-macmillan. pp. 54-75. 2007.
    What is the relation between moral reasons and reasons of “political necessity”? Does the authority of morality extend across political decision-making; or are there “reasons of state” which somehow either stand outside the reach of morality or override it, justifying actions that are morally wrong? This chapter argues that attempts to claim a contra-moral justification for political action typically suffer from a fundamental confusion – a confusion about the nature and expression of practical j…Read more
